CHARLES H. MILLER, OF KALAMA ZOO, MICHIGAN, ASSIGNOR TO THE'FEED WATER PURIFIER COMPANY, OF SAME PLACE.

FEED-WATER HEATER AND PURIFIER.

SPECIFICATION forming part of Letters Patent No. 627,198, dated June 20, 1899,.-

Application filed February 25. 1897. Serial No. 625,017- (No model.)

To all whom, it may concern:

Be it known that 1, CHARLES H. MILLER, a citizen of the United States, residing at the city of Kalamazoo, in the county of Kalama- .5 zoo and State of Michigan,'have invented certain new and useful Improvements in Feed- Water Heaters and Purifiers, of which the fol lowing is a specification.

My invention relates to improvements in internal feed-water heaters and purifiers, and particularly to improvements in that class of internal feed -water heaters and purifiers shown and described in the Patent No. 569,362, issued to Jacob Struben October 13, 1896.

The objects of this invention are to provide an improved internal feed-water heater and purifier which can be inserted and removed from the boiler and which when placed in the boiler will be toward the outside of the same, so that it shall be easilyaccessible to a man entering at the manhole of the boiler,

particularly in the case of horizontal boilers;

second, to provide an internal feed-water heater and purifier which can be easily taken apart and joined together again in sections;

third, to provide an improved feed-water heater and purifier in which the retardingpartitions are easily removable to facilitate the cleaning of the same, and, fourth, to provide an improved feed-water heater and purifier in which the passage-way for the same is extended out in a single trough, so that the water introduced in one part will not have the effect of cooling the water in another part adjacent, as in the construction above referred to. Further objects will appear in the detailed description. I accomplish these objects of my invention by the devices and means described 0 in the following specification, pointed out in the claims, and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a horizontal boiler with a portion of its wallsbroken away 5 to show one of myiniproved feed-water heaters and purifiers. Fig. 2 is an enlarged detail perspective view of the feed-Water heater and purifier removed from the boiler, the supporting-bridging not being shown. Fig. 3 is 5o an enlarged detail sectional view on line 3 3 of Fig. 2, showing the construction'of the receiver-pan for the feed-water heater. Fig. 4

is a transverse sectional view taken on line 4 4 of Fig. 2. Fig. 5 is an enlarged detail view of the end of the trough, showing a modific'ation.

In the drawings similar letters of reference refer to similar parts throughout the several views, all of the sectional views being taken looking in the direction of the little arrows at the ends of thesection-liues.

Referring to the lettered parts of the drawings, A represents the boiler in the usual form. A is the manhole thereof in the usual partition.

D is a supply-pipe leading into the boiler from any desired position, preferably from the top.

O is the receiving-pan, into which the Water is to be delivered.

A long trough, in which the feed-water is heated and purified, is made up in sections B B 13 B. Around one end of each section is secured an additional sheet-metal plate B,

which is securely riveted or joined thereto,

leaving an open space between the ends of the same and the section. This is to receive the end of the next section B. Then the next section B is inserted into the same, the split keys F are fitted over the two partsand 8o join the same securely together. Low partitions E E are inserted into suitable guide-ways or ways at intervals in the trough formed of the sections B to retard the flow of water therethrough. These partitions are lifted out by the engineer or his assistant, and the slime and incrusting material that are deposited therein can then be easily washed out of the sameinto a pail or the lower part of the boiler, where it is washed out in the usual way. A spout is formed on receiving-pan 0, having a suitable deflector to throw the water down in to the trough formed by the sections B. It will be observed that the water is pumped through the delivery-pipe D into the pan C, where it immediately overflows into the trough formed by the sections B, and the water is retarded step by step until it passes around through the same, as will clearly appear from an inspection of the view shown in Fig. 2. An examination of the view shown in Fig. 1 indicates that the front end of the trough is a little raised above the opposite end to insure a prompt fioW of the water from one compartment to the next as it passes through the heater. This device has advantages over any other in that the cold water introduced has no effect on the adjacent troughs until it overflows, and a broad surface is exposed for the overflow to secure a quick heating and consequent complete precipitation of all incrusting material.

I desire to state that my improved heater and purifier can be in a single section or might be joined together by other means, though the means I have shown is preferred by me. Where the manhole of the boiler admits, the sections could be made very much larger, and in fart where the manhole isin the end of the boiler the whole could be made in two sections and sepa rated at the middle of the end where the long telescopic joint is shown, suitable parl itions being placed within the same, as before. The receiving-receptacle C for receiving the water might be integral with the remaining parts of the device. The pipe D could he made to deliver directly in the end of the sections B and Work very satisfactorily. It is preferred to provide some means to prevent the slopping over of the water.

The exact material from which my device is constructed is not essential. It may be sheet metal, cast metal, Wood, pottery, or other material, some good conductor being preferred.

The exact form of the trough in cross-sectionscan be varied. Thesamemayberounded like an eaves-trough or may be made any other desired shape. The exact form I have shown, however, is preferred and possesses great advantage over any other.

Having thus described myinvention, what rifier, the combination of a casing forminga long continuous single trough; suitable removable partitions extending transversely across the same atintervals extending to near the top thereof, dividing the same into cornpartments; and a suitable supply-passage leading into the same to deliver water so that it shall flow through by the force of gravity for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two winesses.
